Change of rings and singularity categories
Oppermann, Steffen; Psaroudakis, Chrysostomos; Stai, Torkil Utvik (Journal article, 2019)We investigate the behavior of singularity categories and stable categories of Gorenstein projective modules along a morphism of rings. The natural context to approach the problem is via change of rings, that is, the ... -
Homological invariants of the arrow removal operation
Erdmann, Karin; Psaroudakis, Chrysostomos; Solberg, Øyvind (Journal article, 2022)In this paper we show that Gorensteinness, singularity categories and the finite generation condition Fg for the Hochschild cohomology are invariants under the arrow removal operation for a finite dimensional algebra. -
